To all whom it may concern:

Be it known that I, WrLLARD A. SPEAK- `MAN, a citizen of the United States of following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to means for controlling and regulating the flow of fluids, and is particularly applicable, though not exclusively so, to faucets, and especially to the kind of faucet known as a mixing-faucet, generally used in connection with hot and cold water; and the object of my invention is t-o provide, primarily, an improved means for regulating the flow of uids and for insuring against leakage when the flow is cut off..

In its broadest feature my invention consists in providinr a plu -cock for regulating and shuttin off flow an combining with it a valve or va ves held to its or their seats by springs and actuated in closing by said sprinvs and in opening by the movements of the plug-cock.

The nature of my improvements will be best understood as described in connection with the drawings, which illustratev a faucet embodying my improvements in what I believe to be their best and most efficient forms, and in which- Figure I is an elevation of my faucet,show ing tIie casing in vertical section on the,v line 1 l of Fig. 2. cet g Fig. 3, an elevation of the plug-cock and connecting-rod shown in Fig. 1, while Figs. 4,'

5, and 6 are respectively sections through the plug-cock, taken on the lines 4- 4, 5 5, and 6 6 of Iig. 3; and Fig. 7 is a cross-sectional view through the ports, taken on the line 7 7 of Fig. 1.

My faucet, as illustrated, is characterized by having two inlet-ports which are provided with valves by which the ports are opened and closed simultaneously and also provided with other means for opening and closing the ports, whereby both may be simultaneously opened and the opening of either regulated so as to edect the desired mixture in the outflowpassage.

By preference the regulating device is a plugcock and the general construction as shown in the drawings, although my inven- Fig. 2 is a plan View of the f aution is capable of very material changes in form and arrangement of parts without departure from its spirit.

In the preferred construction illustrated the casing may be said to be made up of the three parts A, B, and C, the parts A and B being formed with inlet-passages A and B', also with threaded apertures A2 and B2 for the insertion of valves, such passages being closed by screw-caps a and b, and the parts A and B having also exit-ports A3 and B3,

rovided with valve-seats, as shown at a? and s. The parts A and B screw into the central body C of the casing, which is formed with a conical cock-seat, (indicated at C with ports C2 and C3 communicating with the ports Aa and B3, as shown, and through the walls of the cock-seat at C* and C5. As shown, the lower portion of the casing C is also provided with exit-ports C and C7.

D is the'screW-cap of the casing; E, a plugcock working in the seat C and having, as shown, a stem E which extends up through a stuffing-box in the cap D, the stem being formed inte ral with the top E2 ofthe hollow plug-cock, om which also extends downward a partition, (indicated at E3,) which intervenes between the ports E4 and E5, formed in the walls of the cock. The plug-cock, as shown, is' also formed with cams, (indicated at E6 and E7,) formed in the lower portions of its walls and has asegmental stop-lug ES, the ends of which (indicated at Eand E10) limit the rotative movements of the cock by com- ,in `in contact with a stop-lug C8.

is the handle of the cock, which is fastenedgto the stem E and, as shown, provided with a stop and pointer finger F,whieh moves over the surface of a segmental indicator H, attached to or formed with the cas- TOO with inwardly-extending rods J and J ,which 1o 5 y register with a portion of the cock containing the cams E and E7. J 2 J 2 are springs which tend to seat the valves J J.

In Fig. 1 the parts are shown in the position they occupy when the faucet is not in 11o i 17..... H.. i l

use, the valves J J beigfa 'ted on une entrance-ports and the cock turned to such a position as to close the port-openings C4 and C5. The first motion of the handle F and cock E brings the cams E6 and E7 into contact with the valve-stems J forcing the valves J J outward, so as to open the portions of the entrance-ports which these valves have previously closed, and during all other motions of the plug-cock the valves J J remain o en until the handle is again returned to the c osed position. (Shown in Figs. 1 and 2.) The further opening movement of the plug-cock brings the cock-port E4 into registry with the port opening C4, which is generally that through which the cold water enters the faucet, the motion of the cock gradually opening this port until when it is o ened to the maximum the port E5 of the coc r begins to register with the port C5 of the casing, in which the further movement of the cock contracts the o enng through the port C4, closing it at or about the time when the port C5 is fully opened. It is generally desirable to x some automatic stop by which movements of the cock will be arrested at the point where the normal desirable mixture of hot and cold water is secured, and this I accomplish by means of the adjustable stop I and stop-finger F.

The reversed movements of the cock are of course just the reverse of those described for its opening movement, the valves J J remaining open until the cock and handle are turned to closed osition.

Aside om other advantages of my constructions it will be noted that I avoid the leaking which is very frequently incident to the use of plug-cocks by providing the independent closing valves in the inletports, which supplement the cock and close the ports positively when the faucet is not in use.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A casing having a cock-seat and a valve seat or seats, in combination with a plugcock working in the cock-seat, a valve or valves adapted to seat themselves on the valve seat or seats aforesaid, springs acting to seat said valves and means actuated by the turning of the plug-cock to open its ports and acting to open the valve or valves and by the turning of the cock to close its ports to release the valve or valves and permit the springs to close them.

2. A casing having communicating ports, a cock-seat interposed in one or more of said ports, and one or more valve-seats also interposed in said ports, in combination with a plug-cock Working in the cock-seat, a valve or valves ada ted to seat themselves on the valve-seats a oresaid, springs acting to seat said valves, and means actuated by the move- 'ment of the cock to open the ports controlled by it operating to open the valves and by the movement of the cock to close its ports to re-` lease the valves permitting the springs to close them.
